Query enhancement system and method for constructing elastic field based on time delay

Abstract

A query enhancement system for constructing an elastic field based on a time delay, including: dividing a network node to obtain a set of containers composed of several containers, wherein the containers are nested and each container includes a management node for performing node organization, neighbor maintenance and query services within the container. Further, a query enhancement method for constructing an elastic field based on a time delay includes: carrying out same-layer non-intersection full-coverage division on a network node to obtain a set of containers that are nested, and execute a query flow without a given low time delay requirement which uses an existing query technique and a nearby query flow with a given low time delay requirement which uses a distributed nearby querying method to carry out a nearby query; with an actual query time delay index Ti less than the requirement of an upper time delay limit Ts.

Description

[0001]The present application claims the priority of the Chinese patent application No. 201710841537.4 filed on Sep. 18, 2017 and entitled “Query Enhancement System and Method for Constructing Elastic Field Based on Time Delay”, the contents of which are incorporated by reference herein in its entirety.TECHNICAL FIELD[0002]The present invention belongs to the field of network technology and network communication technology, and in particular relates to a query enhancement system and method for constructing an elastic field based on time delay.BACKGROUND ART[0003]In the prior art, distributed query (query) includes: Range query (Range query), aggregation query, Skyline query and Top-k query. Wherein Range query (Range query) means to search all resources with a single or multiple attribute values being within a certain continuity interval, for example, an attribute identification can be acquired through a position-sensitive harsh algorithm on the basis of Chord, and mapping between a...

Benefits of technology

[0008]An object of the present invention is as follows: in order the solve the above problems existing in the existing query enhancement system and method, the present invention provides a query enhancement system for constructing an elastic field based on time delay, thereby effectively solving problems of distributive organization and query, preferably processing application scenarios with given low time delay requirements in information-centric networking (ICN), and realizing distributed nearby query in terms of a position relationship from the near to the distant.

[0046]The present invention has the following advantages: aiming at various time delay sensitive applications including low time delay and high reliability, the present invention discloses a query enhancement system and method for constructing an elastic field based on time delay, and satisfies request processing requirements of returning query results within a given low time delay. Through a distributed nearby query in terms of a position relationship from the near to the distant, and through priority processing of low time delay application scenarios, overall query time can be shortened dramatically.

Problems solved by technology

1) Although a content space is nested and layered through a container or structured technique according to network characteristics, however, the existing partition method is independent of response time and application requirements of a system, while structural service performance independence obviously cannot directly satisfy requirements of time delay;

2) Under an environment which has a higher requirement on mobility and security, an elastic scalable query method according to requirements of response time or performance requirements cannot be provided, and search efficiency and precision cannot be ensured while improving resource utilization rate.

In addition, in the existing distributive query methods, response time of query is generally related to node scale, size of query region, and number of attributes of resources in query (that is, spatial dimension), however, query results cannot be returned within a fixed time delay.
